Membrane Bio-Reactor – Sewage Disposal To You and Me – the Helicopter Carrier OCEAN, currently a fair way into a 15 month overhaul programme at Babcock’s Devonport Royal Dockyard, has seen work completed on schedule in preparation for the installation (by Babcock) of a first of class Membrane Bio-Reactor, a significant proportion of the vessel’s current upgrade package.   The new Membrane Bio-Reactor replaces the ship’s existing sewage treatment system and will be capable of processing both waste water and sewage (black and grey water, galley, laundry, sink and shower waste).    This will mean that OCEAN will be in full compliance with current and future planned IMO and MARPOL regulations due to come into force in 2015, enabling the ship to operate globally.
